13 Claims.

The principal object of my invention is to provide a coin selector for pay telephones and like that will eject all slugs and spurious coins before they enter the device they are intended to operate.

A further object of this invention is to provide a coin selector for pay telephones and like that electrically selects or differentiates between coins and slugs when a manually operated lever is actuated and returns all spurious coins to the user allowing the genuine coins to fall into the device to be operated.

A still further object of my invention is to provide a coin selector for pay telephones and like that will hold the coin within the selector unit until the manually operated lever is actuated for the identification of the coin.

More specifically the object of this invention is to provide a coin selector for pay telephones and like that depends upon the engraving on a genuine coin for its actuation.

A still further object of my invention is to provide a coin selector for pay telephones and like that is economical in manufacture, durable and efficient in use.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Fig. 1 is a side sectional view of my complete coin selector as attached to a portion of a pay telephone.

Fig. 2 is a sectional view of a portion of my device showing the coin selectors.

Fig. 3 is a top plan view of the shuttle and coin followers of my device.

Fig. 4 is a schematic wiring diagram of the electric circuit of my device.

Fig. 5 is a rear cross-sectional view of a portion Olf my device showing the shuttle and the guide bars upon which it rests.

There have been numerous attempts to create a device for the elimination of slugs and spurious coins from pay telephones and similar coin operated machines. The majority of these rely on a magnet for pulling the spurious coins out of the device before they operate the device. However, these devices are only successful on ferrous metals and are of no value when copper, brass, nickel. aluminum or similar slugs are used. Also some types work on the principle that all slugs ust 27, 1936. Application have a hole in the center and these devices only eject those slugs which do have a hole in the center. None of the devices now in use depend upon the peculiarities of the engraved portions of my coins. There has been a distinct need for a device that will successfully prevent the use of slugs in operating slot machines. Many thousands of dollars are lost each year by owners of slot machine dispensers and automatic pay devices through the use of slugs in those machines as well as loss of merchandise through this fraudulent means. There is the ever-present danger of jamming the machine, thus necessitating repairs and costly delays. I have overcome these difficulties and supplied a need as will be appreciated and as is hereinafter more fully set forth.

Referring to the drawings, I have used the numeral II) to designate the housing of my device including the housing of an ordinary pay telephone having situated therein a return slot II and a coin slot I2 as shown in Fig. 1. The numeral I3 designates the coin entrance and as is well known, there are generally three of such entrances on a pay telephone, one to receive nickels, one to receive dimes and one to receive quarters. The numerals l4, l5 and I6 designate coin followers of the approximate diameter of a quarter, dime and nickel respectively and constructed of an insulating material such as hard rubber fiber or the like. These followers each have a shaft secured to the rear central portion and extending rearwardly and which I have designated by the numerals l1, l6 and I9 respectively. These shafts in turn are slidably mounted in a shuttle 20 which is of box-like construction and has its forward and rear surfaces constructed of an insulating material as shown in the drawings.

The numerals 2|, 22 and 23 designate stops secured to the rear end of each of the rods IT, IS and I9 respectively which limit the forward sliding movement of the rods and determine the extended position of the followers [4, I5 and IS. The numerals 24, 25 and 26 designate coil springs about the rods IT, IS and i9 and partially compressed between the front surface of the shuttle 2D and the rear surface of the fol owers I4, l5 and I6 respectively. I have used the numerals 21 and 28 to designate guide rails secured to the housing ID of the device and upon which the shuttle 20 is slidably mounted as shown in Figs. 3 and 5 of the drawings. Rigidly secured within the housing of the device and extending upwardly near its forward portion is the insulative wall 29 which supports the coin plates 39, SI and 32 which are spaced from and concentric with the followers |4, l5 and I6 as shown in Fig. 1. These plates each have the electric contact feeler points 33, 34, 35 and 36 which protrude through their respective plates a slight distance as shown. As corresponding numerals designate respective contact points and are electrically connected as shown in the schematic diagram in Fig. 4 of the drawings, they will be referred to as a single unit. It will here be noted by reference to Fig. 1 that the rearward or contact faces of these coin plates are directly parallel to and under the forward wall of the coin slot |3 so that a coin dropping through the slot must drop between its respective follower and coin plate. I have used the numeral 31 to designate a shaft slidably mounted within the housing of the device, extending through the forward wall of the device, and having on its forward end a knob 38 to facilitate the manual actuation of the shaft 31. Pivotally secured to the rearward end of this shaft is the lever 39 which has one of its ends suitably pivoted on a bearing secured to the guide rail 28 and has its other end pivotally secured to a link 40 which is in turn pivotally secured to a bearing 4| which is rigidly secured to the rear face of the shuttle 25 for actuating the same and as is shown in Fig. 1 of the drawings.

Thus by manually pushing on the knob 38 the shaft 31 will be pushed rearwardly actuating the lever 39 and pushing the shuttle 20 forward. Positioned below and between each set of follower and coin plates is the stop and deflector plate 42 which is pivotally secured near its lower marginal edge to the housing ll) of the device. This deflector plate 42 has a semi-circular cut-out portion which is also widened and rests adjacent the lower half of the coin plates as shown in Fig. 2 of the drawings. Pivotally secured to the deflector plate 42 near its central portions is the bar 43 which extends rearwardly and has its rearward end pivotally secured to a lever 44 which is secured to the central portion of a magnet arm 45 which is, in turn, pivotally secured to the guide rail 28 as shown in Fig. 1.

This lever 44 is held in its n utral central position by the opposing coil springs 46 which have their free ends secured to the housing and which tends to hold the lever in a vertical position. The numeral 41 designates a fork integrally formed on the bar 43 and extending downwardly and which receives a pin 48 secured to a lever 49 as shown in the drawings. This lever 49 is pivotally secured to the guide rail 28, extends up one side wall of the housing ll] of the device and has its other end pivotally secured to a link 50 which in turn is pivotally secured to the operating arm of a bridge switch 5| which is of the common type. I have used the numerals 52, 53 and 54 to designate three circuit breaker magnets having the breaker arms 55, 56 and 51 respectively and the contact points 58, 59 and 60 respectively as shown in the drawings. The numeral 6| designates a selector magnet operatively arranged above the forward end of the magnet arm 45. The numeral 62 designates a similar selector magnet operatively arranged adjacent the rearward end of the magnet arm 45. These magnets are so arranged that when the magnet 6| is in operation the magnet arm is drawn upward at it forward end moving the lever 44 forwardly operating the bar 43. Similarly when the magnet 62 is energized, the rearward end of the arm 45 is drawn upwardly pulling the lever 44 rearwardly and actuating the bar 43. The numeral 63 designates a contact arm secured to the forward face of the shuttle 20 as shown in Figs. 1 and 3 of the drawings. The numeral 64 designates the stationary contact arm secured to the guide rail 28 insulated from contact therewith, and capable of receiving the contact arm 63 when the shuttle 20 is moved forwardly. Thus it will be seen that when the knob 38 is manually actuated, the shuttle will move forwardly as hereinbefore described, closing the contact between the arms 63 and 64. When pressure is released on the knob 38, the rod 31 will be pulled to its more forwardly position by virtue of the spring 65 which has one end secured to the rod 31 and its other end secured to the housing Ill as shown in Fig. 1.

Referring to Fig. 4 of the drawings, I have used the numerals 55 and 57 to designate the input electric wires which are in communication with a suitable source of power such as the telephone line voltage. When thus connected with the telephone line voltage, these input wires 65 and 51 are connected through the ordinary switches within the telephone, such as the receiver switch. The wire 66 is in communication with the contact points 33 of the contact plates. The numeral 58 designates a lead wire in communication between the wire 66, two contacts of the switch 5|, the stationary contact 64 of the shuttle operated switch and the breaker 55 of the electromagnet 52. The numeral 69 designates a lead wire in electrical communication between the contact points 34 of the contact plates and one end of the windings of the electromagnet 52 which is also connected to the lower end of the windings of the magnets 53 and 54, to the lower end of the magnets 6| and 62 and thence connected to the wire 6! as shown in the drawings. The numeral Ill designates a lead wire in electrical contact with the contacts 35 of the plates and in communication with the upper end of the magnet coil 53. The numeral 1| designates an electric lead line in communication With the contacts 36 of the contact plates and in electrical communication with the upper nd of the windings of the magnet 54. The numeral 12 designates a wire in communication between the contact 58 of the magnet 52 and the arms 56 of the magnet 53. The numeral 13 designates a lead wire in communication beween the contact 59 of the magnet 53 and the arm 51 of the magnet 54. The numeral 14 designates a lead wire in communication between one contact of the switch 5|, the contact 6-3 of the magnet 54 and the upper end of the windings of the magnet 62. The numeral 15 desig nates a lead wire in communication between the magnet 6|, and also in ntact of the switch 'ihematic diagram.

communication with one 5| as is shown in the the lever 49 and the link 53 which operate for purposes of identification of relative action in the schematic diagram. Any suitable form of release switch mechanism may be provided for breaking the holding or look-up circuit which is established throu h the bridge switch 5| to either of the magnets 5| and 82, this circuit breaking function occurring at the end of the operating cycle, such as just at the end of the backward or restoring motion of the shuttle 2|]. In telephone adaptations of my invention, this release function can be performed by a switch within the telephone, such as the aforesaid receiver switch.

The practical operation of my device is as follows: As all of the coin plates operate in the same manner, I shall use the one actuated by a dime as an illustration.

The coin is dropped through the slot I3 and will drop between the follower l5 and the plate 3|, resting on the concave portion of the deflector plate 42. After the coin has been dropped into the device the knob 38 is pushed rearwardly thus moving the shuttle 20 and moving the follower l5 forwardly forcing the coin against the contacts of the plate 3|. It will here be noted that all coins are engraved and are quite irregular in facial contour. Thus all four of the contact points 33, 34, 35 and 36 will not be short circuited by the coin. As the rod 31 is pushed farther rearwardly, the shuttle will move forwardly against the compression of the spring 25 until contact is made between the contact arms 63 and 64. This closes the circuit between the source of current and the electromagnet Bl. The magnet 6| thus being energized will pull the forward end of the magnet arm 45 toward it, thus pivoting this arm and moving the lever 44 in a forwardly direction. This causes the deflector plate 42 to pivot forwardly and at the same time operates the bridge switch 5| thus keeping the magnet 6| in circuit so that when pressure on the knob 38 has ceased, the spring 65 will return the knob as well as the shuttle and its appendant mechanism toward its normal position. As the bridge contact switch holds the circuit for a time, the plate 42 will remain in its upwardly and forwardly sloped position after the pressure on the coin has ceased, thus deflecting the coin downwardly and through the coin chute I2 where it will operate the mechanism. In those telephone adaptations of my invention which use the receiver switch as the release switch of the device, when the shuttle 23 is moved back to its rearward position, and the receiver is placed back on the hook of the telephone at the completion of the call, the current is thereupon cut off by the receiver switch, with the result that the neutralizing springs 46 will return the mechanism to a normal position, as the magnet 6| will not remain energized after such interruption of the current supply.

If a slug or other spurious coin is inserted in the coin slot l3, it will take a similar position between the follower l5 and the plate 31. However, when the shuttle s actuated by the rod 31, the follower will force the counterfeit coin against the contacts on the plate 3|. This short circuits all of the contacts 33, 34, 35 and 35 thus actuating all of the magnets 52, 53 and 54 closing the arms 55, 56 and 51 upon their respective contact points 58, 59 and 5!], completing the electrical circuit to the magnet 62. As the magnet 62 is energized, it will pull the rearward end of the magnet arm 45 upwardly thus moving the lever 44 rearwardly so that as the pressure is released the spurious coin will drop into the chute II which returns the coin to the user without actuating the mechanism of the device intended to be operated. The action of this counterfeit coin detector circuit rotates the switch 5! in the other direction closing and retaining the contact between the source of electrical energy and the magnet 62 until the device has returned to a normal rearward position, at which time the placing of the receiver back on the hook deenergizes the magnet 52 and restores the switch 5| and deflector plate 42 to their normal positions, in the same manner described above. It will be noted that it is necessary to short circuit all four of the contact points before the magnet 62 is actuated due to the relays 52, 53, and 54; thus if two or three points should touch on the engraving of a genuine coin, it will not actuated the return mechanism. It is very unlikely that all four contact points would touch a genuine coin. If, however, a smooth coin is placed in the device, it will return it to the user, so that he will not be out his money.

It will be noted that the first pressure of the follower on a slug will immediately short circuit all of the contacts on the coin plate, thus moving the plate 42 for the rejection of the spurious coin. This moves the switch 5| to hold the contact and even when the knob 38 is pushed to its rearmost position and contact is made between the contacts 63 and 64 closing the circuit to the magnet iii no counter action will take place.

After the magnet arm has been drawn adjacent to the magnet 62 the rearward end of the arm 45 will be at such a distance from the magnet 5| that the magnetic field of the magnet M can not possibly overcome the magnetic field of the magnet 62 and move the arm 45 in the other direction.

Thus it will be seen that I have provided a coin selector for telephones and the like that will reject all spurious coins, slugs and worn coins before they enter the mechanism they are intended to actuate. My device will work on any type of metallic substance that will conduct an electric current. It is simple to operate, having only one manual control and can not be tampered with without destroying the device.

Some changes may be made in the construction and arrangement of my improved coin selector for pay telephones and the like without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
